Glencoe algebra 1 7-3 practice rational exponents answers

horsena [70]2 years ago

The expressions are illustrations of rational exponent expressions

The equivalent expressions are (8x)^\frac 12 = 2\sqrt{2x, 6z^\frac 12 = 6\sqrt z and \sqrt{19} = 19^\frac 12

<h3>How to simplify the rational exponent expressions?</h3>

From the complete question (see attachment), we are to simplify or rewrite the following expressions

(8x)^\frac 12

6z^\frac 12

\sqrt{19

For (8x)^\frac 12, we simply apply the exponent rule of indices

(8x)^\frac 12 = \sqrt{8x

Express 8 as 4 * 2

(8x)^\frac 12 = \sqrt{4 * 2x

Take the square root of 4

(8x)^\frac 12 = 2\sqrt{2x

For 6z^\frac 12, we apply the exponent rule of indices

6z^\frac 12 = 6\sqrt z

For \sqrt{19, we apply the the same rule

\sqrt{19} = 19^\frac 12

Hence, the equivalent expressions are (8x)^\frac 12 = 2\sqrt{2x, 6z^\frac 12 = 6\sqrt z and \sqrt{19} = 19^\frac 12

Ray purchases a paperweight and wants to cover it in paper. He creates the picture below to show the net of the figure. Ray only
sergey [27]

The square inches of paper Ray needs are equal to the area of the sides he wants to cover.

<h3>What is the area?</h3>

The area of an object refers to the surface or space occupied by the object.

<h3>Why is the area important?</h3>

In this situation calculating the area is essential because by doing this, Ray can know how much paper he needs.

<h3>How to calculate the area?</h3>

Different formulas can be used to calculate the area depending on the shape of the object.

  • Rectangle: Side x side
  • Triangle: 1/2 base x height
  • Circle: πr2

This means to know the exact answer, Ray needs to calculate the area of the sides he wants to cover and this is equal to the paper he needs to buy.

Note: This question is incomplete because the picture was not attached. Due to this, I answered it based on general knowledge.

Which reaction will most likely take place based on the activity series? li &gt; k &gt; ba &gt; ca &gt; na &gt; mn &gt; zn &gt;
Ivenika [448]

The only reaction that will most likely take place based on the activity series is; C: Ba + Na₂CO₃

<h3>Activity Series</h3>

From the activity series given, we can say that during a displacement reaction, the more reactive metal will always displace the lesser reactive metal from a compound.

Let us look at each of the given options;

A) Ag + FeCl₃

From the activity series, Silver(Ag) is less reactive than Iron(Fe) and as such Silver cannot displace iron from its' compound.

B) Zn + CaO

Zinc (Zn) is a less reactive metal than Calcium (Ca), so it cannot cannot displace Calcium from its' compound.

C) Ba + Na₂CO₃

Barium (Ba) is a more reactive metal than Sodium (Na), and therefore Barium will displace sodium from its compound in a displacement reaction.

D) Cr + KNO₃

Chromium (Cr) is a lesser reactive metal than Potassium (K), and it therefore cannot displace Potassium from its compound.

Complete question is;

Which reaction will most likely take place based on the activity series? Li > K Ba > CaNa > Mn > Zn > Cr> Fe> Cd Ni > H > Sb > Cu > Ag > Pd > Hg > Pt

A. Ag + FeCl₃

B. Zn + CaO

C. Ba + Na₂CO₃

D. Cr + KNO₃
